Thanks for sharing, that's exactly the kind of production feedback I was looking for.
Out of curiosity, what type of project are you running where p95/p99 latency and websocket reconnects have become important?
Are you running your own infrastructure or using a managed RPC provider?

What RPC problems are Solana projects actually dealing with right now?

Success Fees, Sonic SVM North Star, x402 on Solana June Report, .sol gLTD
https://preview.redd.it/l4m84yoikgch1.png?width=960&format=png&auto=webp&s=2d0924a5493dd7514ee5f86c375e6acaf7a5b152
*This week is about incentives finally catching up to reality, whether that's validators getting paid to actually land transactions, autonomous agents paying their own way per request, or a DAO governance model that let 7 wallets drain $20M because nobody else showed up!*

**🔥 Success Fees**
A new proposal would add an optional success fee only when a transaction actually executes successfully, on top of the existing priority fee.
Under the current fee model, users pay priority fees whether or not their transaction succeeds. Validators get paid for including a transaction in a block regardless of outcome, which means there's no direct economic reason for them to prioritize execution success over simple inclusion. 
The proposal targets that mismatch: it ties part of validator compensation to the actual job they need to do, packing transactions into blocks in a way that lets them land.
The mechanism works as a stacked fee. The base fee and priority fee still get charged on failure, same as today. The success fee is only debited after execution. If the account can't cover it, the transaction gets marked with an `InsufficientFundsForSuccessFee` error. 
It would be implemented as a new Compute Budget instruction or a TxV1 field, defaulting to zero so it's fully opt-in. The idea is to bring tipping that already happens out-of-protocol, through Jito bundles and similar side channels, into the protocol itself.
The discussion has surfaced one central, unresolved technical tension: if the success fee doesn't influence transaction ordering, it doesn't solve the landing-rate problem it's meant to solve. But if it does influence ordering, it needs to be reserved or escrowed at pack time, not just declared, because otherwise leaders are scheduling based on a fee they haven't actually secured. 
*There's been a handful of fee-related SIMDs proposed lately to address fee structure and inflation, and it's easy to lose track of which ones matter. This one will, once the remaining questions have been answered.*

# 🌠 Sonic SVM North Star
Sonic SVM launched North Star, a private execution layer that gives Solana agents and dApps their own dedicated, temporary runtime for high-frequency workloads.
An app opens a session with one SDK call, delegates its accounts into a private runtime, then runs its existing Solana program unchanged, same binary, same compute units, at over 1 million TPS with near-zero per-transaction cost. 
When the session ends, all state settles atomically back to Solana, with correctness enforced by delegated accounts locking on L1 while the session runs rather than by trusting a sequencer.
The target workloads are ones that can't tolerate shared blockspace:
* Trading agents that reprice continuously and settle only the final result
* Pricing agents pushing orderbook updates every 20ms
* Multi-agent systems that need to coordinate reads and writes at speed before settling together.
[EvaDotFun](http://eva.fun/?ref=blog.colosseum.com), an on-chain agent arena where autonomous agents compete and build reputation through execution, is the first app built on North Star.
*Agents making decisions every block need throughput that shared blockspace can't guarantee. North Star is a bet that on-demand runtimes are how that gets solved.*

# 🤖 x402 on Solana
June was a breakout month for agent-to-agent payments on Solana via the x402 protocol. AWS opened a monetization pipeline letting content publishers charge AI crawlers and get paid instantly in stablecoins, routed over x402 on Solana rather than blocking bots outright.
On the trading side, ClawPump crossed $100M in combined spot and perpetuals volume, driven by more than 5,000 autonomous agents trading around the clock, and went on to win the Colosseum Frontier Hackathon. 
Quicknode began offering free service up to 1M requests a month per agent using x402, lowering the barrier for agents to access infrastructure without prepaid API keys.
Metaplex shipped Agent Profiles and an onchain Agent Registry, giving agents verifiable identity and action history, a piece OpenCovenant picked up immediately for its own agent reputation system.
Beyond those, the month saw a wave of smaller integrations across identity, inference marketplaces, and agent tooling, all converging on the same pattern: agents paying per request instead of relying on human-managed accounts or fiat rails.
*x402 is turning from a demo into infrastructure that major platforms like AWS are building on top of, and Solana is becoming the platform for agentic payments.*

Protocol 27, codenamed Zipper, [went live on Stellar mainnet on July 9](https://x.com/StellarOrg/status/2074902336393060391), shipping auth delegation, bundled signature entries, and replay protection. That same day, [Alchemy joined Stellar's tier-1 validator set](https://x.com/StellarOrg/status/2074912016347668655), participating directly in SCP consensus. The UNDP and SDF [extended their partnership](https://stellar.org/press/undp-and-stellar-development-foundation-extend-partnership-to-scale-proven-digital-payment-solutions) to make blockchain-based digital payments a permanent UNDP capability through 2027, scaling results from five country pilots.
# Protocol 27 and Network Infrastructure
Protocol 27 activated on Stellar mainnet July 9. The Zipper upgrade ships auth delegation as a first-class smart account feature, combines all signer auth into one entry per transaction, simplifies simulation, and prevents signature replay.
CAP-711 adds built-in delegation support for modular custom accounts. CAP-712 fixes a signature vulnerability: the standard authorization pre-image did not include the signer's address, creating a replay risk when private keys are shared across accounts during simultaneous signer rotation. Both CAPs were discussed at the [July 8 Stellar Developers Meeting](https://www.youtube.com/watch?v=5O1cDDGv7_o).
Alchemy now participates directly in SCP consensus as a tier-1 validator, adding to its existing Stellar RPC and read support. At Thursday's developer meeting, u/0xkaancar presented [CAP-0084 and CAP-0085](https://github.com/stellar/stellar-protocol/tree/master/core) for community review.
# Institutional Activity
The UNDP and SDF [extended their partnership](https://stellar.org/press/undp-and-stellar-development-foundation-extend-partnership-to-scale-proven-digital-payment-solutions) through 2027, converting five country pilots into standing UNDP operational infrastructure. Pilots across Haiti, Kenya, Syria, Guatemala, and The Gambia cut transaction costs from 10% to 2% and achieved 100% reliability in low-connectivity settings.
M1X Global [raised $8.5 million](https://www.prnewswire.com/news-releases/m1x-global-announces-further-funding-led-by-paradigm-totalling-8-5-million-302819729.html) led by Paradigm to scale USDM1, a U.S. Treasury-backed sovereign bond issued natively on a public blockchain by the Republic of the Marshall Islands. DFNS provides wallet and banking infrastructure; USDM1 is integrated into institutional collateral workflows at Bank of America, Citadel Securities, and Virtu Financial and funds quarterly UBI payments to Marshall Islands citizens. DFNS [detailed the setup](https://dfns.co/article/announcing-m1x) across Stellar, Canton, and Solana.
STBL [published Q2 milestones](https://x.com/i/article/2075543827264499712): USST reached 5 million tokens minted on Stellar, and Hashlock and Cyfrin completed security audits. OpenZeppelin and T-REX Network [announced a partnership](https://www.openzeppelin.com/news/openzeppelin-and-trex-network-partner-to-advance-institutional-compliance-infrastructure) to deliver ERC-3643 as an audited library component and extend T-REX Protocol to non-EVM networks, with a Stellar-native implementation already complete.
# Consumer Wallets
Normal Finance [expanded its non-custodial wallet](https://normalfi.substack.com/p/normal-is-now-multi-asset) to support Bitcoin, Ethereum, and Solana alongside XLM in a single app. Stellar remains the core settlement layer; USDC deposits earn yield via Blend and DeFindex.
[MoneyGram is now live inside Normal Finance](https://normalfi.substack.com/p/moneygram-is-live-in-normal) as a cash on/off-ramp, covering 500,000+ locations across 200+ countries. Users deposit cash and receive cryptocurrency directly, or reverse the flow to cash out.
# Developer Infrastructure
OpenZeppelin published [step-by-step guides](http://docs.openzeppelin.com/relayer/1.5.x/guides/stellar-relayer-gcp-operator-guide) for running its Relayer Service in teams' own AWS and GCP environments, covering compute, state management, key security, fee bumping, and RPC failover.
[Stellar Raven](https://x.com/i/article/2075371500324929536), an MCP server built by u/kalepail, aggregates Stellar documentation, tools, and community intelligence into a single connection for AI agents and builders. The companion [Stellar Skills directory](https://skills.stellar.org/) curates context files teaching agents about Stellar contracts, SDKs, and tooling. [Mercury (Xycloo Labs)](https://x.com/xyclooLabs/status/2074208030837878880) launched as a paid, production-ready indexing service after open testing, covering Soroban events, webhooks, retroshades, and RPC access.
# DeFi
DeFindex's APY Stabilizer received a [completed audit from Rvinci Security](https://twitter.com/rv_inc/status/2075591375119138929). The two-week engagement, concluding June 2026, covered role-based access controls, fee bounds, accounting invariants, and cross-contract interaction security across two Soroban contracts. All findings were addressed or acknowledged. DeFindex ranks in the top 10 DeFi protocols on Stellar by TVL.
The July 2026 [SCF Demo Day](https://www.youtube.com/watch?v=unddHWrZnOs) featured 75 awarded projects live on Stellar. Highlighted presentations included Inference, a formal verification language, and Lumen Loop, an ecosystem content aggregator and project directory. The SCF has awarded $7.7 million across 75+ projects in 2026.
